The term "PS4 Tool Downgrade v1.00 EXE download patched" refers to a specific software tool designed to downgrade a PS4 from a newer firmware version to version 1.00, which is the original firmware version that shipped with the earliest PS4 models. This tool, or variations of it, have been sought after by users and developers looking to restore their consoles to an earlier state.
There is named "PS4 Tool Downgrade v1.00.exe" that can downgrade your PS4's system firmware simply by running a file on a PC. Any file claiming to be a "patched" version of such a tool is likely malware or a scam . The Reality of PS4 Downgrading
The mention of a "patched" EXE file implies that the tool has been updated or modified to address previous issues or to bypass certain security measures. This patching could enhance the tool's compatibility, safety, or success rate in downgrading the PS4. The promise of an easy "v100" downgrader makes
All PS4 firmware updates (PUP files) are signed with Sony’s private RSA-2048 key. The console’s bootloader contains the public key. For a downgrade to happen via a PC tool, that tool would need to generate a valid PUP file for 1.00 that is signed by Sony.

Consequently, the "patching" of these exploits is not merely a nuisance to users, but a necessary business defense. The rarity of the working downgrade tools serves as a natural barrier, limiting high-level access to a small fraction of consoles and preserving the overall integrity of the PlayStation Network for the general user base.
The concept of downgrading the PS4's (e.g., from 10.50 to 9.00) is a completely different and far more difficult challenge. This is what most people mean when they search for a "downgrade tool." It is not a software process and cannot be done with an .exe file. The PS4 employs multiple, redundant security checks that actively prevent downgrading to an earlier firmware version. A "downgrade" is only achievable through a complex, high-risk hardware procedure known as a "System Software Revert."
